FieldPosition

Field Position is a simple type used by the Format module and its submodules to identify fields in formatted output.

Required Header

#include <utils_i18n.h>

Overview

Fields are identified by constants defined in *_format_field_e enumerations. The only fields currently supported are the fields accepted by the date formatter, see i18n_udate_format_field_e. Field position keeps track of the position of the field within the formatted output with two indices: the index of the first character of the field and the index of the last character of the field. One version of the format function in the various Format modules requires a Field Position object as an argument. You use this format function to perform partial formatting or to get information about the formatted output (such as the position of a field).
